Answer:
The correct answer is D. The South and the Southwest are considered part of the Sunbelt.
Explanation:
The Sunbelt is a region of the United States that extends from the Atlantic coast of the Southeast to the pacific coast of the Southwest. This includes the states located approximately between parallels 37 and 38. The Sun Belt has seen its population increase due in part to internal migration motivated by the withdrawal of the birth explosion and in part to the influx of immigrants.
Arizona, California, Florida, Nevada, New Mexico, Texas, Georgia, and South Carolina are usually considered part of the Sun Belt; Louisiana, Mississippi, and Alabama can also be included. Some authors consider that Arkansas, Colorado, North Carolina and Tennessee are part of it, even though their climates are colder than the other states of the group. In any case, these states have a high proportion of sunny days.
